Mueller Incorporated details must be followed as a minimum to ensure appropriate warranties be issued. Mueller
Incorporated assumes no responsibility for any problems which might arise as a result improper installation or any
personal injury or property damage that might occur with the products use.
Mueller is providing the following installation instructions and details as a guideline, to show a knowledgeable,
trained erector, parts placement one to another. All local building codes in project specifications should be followed,
however, in all cases, good roofing practices, and good workmanship should be employed when constructing a
roofing system using Mueller products. These procedures and details are not intended to cover all instances, building
requirements, designs, or codes. These details may require changes or revisions for each project, as conditions vary
from project to project. The details provided are proven methods of construction.
Mueller Incorporated does not consider the installation of a standing seam roof to be a
do-it-yourself project. Work should be performed by experienced craftsmen familiar with
metal roofing products and current industry standards.
This installation guide is provided to Mueller customers and contractors as a basic recommended procedure for
the correct assembly of the Mueller Snap Lock Standing Seam Roof System. This guide is intended to be used in
conjunction with the erection drawings to help plan and organize the installation of the Mueller Lock Standing
Seam Roof System. The erection drawings govern specific part arrangement and identify the applicable roof
conditions. The instructions will help identify parts, establish the installation sequence, demonstrate correct
assembly, and point out areas or procedures requiring special emphasis or attention.

This installation guide applies to the Mueller Snap Lock Standing Seam Roof System. Custom roof conditions,
including custom details and instruction, will be covered by the erection drawings. In case of conflict between this
installation guide and the erection drawings, the erection drawings will take precedence.
CUSTOMER’S RESPONSIBILITY
Suitability of details
It is the responsibility of the customer (or designer) to ensure that the details meet particular building requirements
to assure adequate water tightness. It is the customer’s responsibility to determine suitability of supplemental details
for any claims arising from improper detail selection by others or faulty installation of any kind.
Suitability of substrate or structure
It is the responsibility of the customer (or designer) to determine suitability of structure, or substrate for the MSL
panel system. It should be code-compliant and properly engineered and constructed for a structural standing seam
roof system. It must be true and aligned to avoid panel distortion. MSL panels offer little or no diaphragm stability to
the structure, and may not be relied upon for diaphragm support.
Suitability of roof accessories
Mueller may pass along vendor information to its customers for insulation, preformed roof curbs, hatches, vents,
pipe flashings and other ancillary roof accessory items as well as tools and specialty fasteners. This is done as a
convenience to the customer and is not to be construed as an approval of any particular roof accessory item for
any given application. It is the responsibility of the customer to qualify other vendors and products with respect to
quality and suitability for any particular application. Mueller assumes no responsibility for suitability or performance
of materials and accessory items furnished by other vendors.

• Panels should be installed straight and accurately.
• Roof clips shall allow for thermal movement and must be installed in strict accordance with Mueller erection
drawings with respect to type and quantity of fasteners as well as clip spacing along the panel seam.
• Thermal movement of panels must be considered when attaching to adjacent constructions and materials.
• All areas of roof must have positive drainage of 3:12 pitch minimum and not allow ponding in any area of the roof.
4
• Compatibility of adjacent materials (not furnished by Mueller) should be verified.
• No penetrations whatsoever shall be placed in the panel system by fasteners or other roof ancillaries except as
shown on the erection drawings.
• Only Mueller furnished or approved sealants shall be used, and only as shown on drawings and within this manual.
• Some field cutting and fitting of panels and flashings is expected and considered part of normal installation.
• “Oil Canning” of the flat portion of metal panels is inherent to metal panels and a common industry phenomenon.
It shall not be considered cause for rejection.
• All flashings, closures, and accessories shown on the erection drawings shall be provided by Mueller unless noted
otherwise. Installation procedures shall be in accordance with Mueller printed instructions, details, approved shop
drawings and the highest industry standards and practices.
Trade Knowledge and Practices
The customer (and/or) installer of the roof system is responsible for the safe execution of the work. Metal roof

IMPORTANT INFORMATION
Roof Safety Considerations
OSHA
The Occupational Safety and Health Act (OSHA) has developed many regulations applicable to the installation of this
or any other roof system. These regulations, identified as Part 1926, Safety and Health Regulation for Construction,
are available from any government book store. The objective of the OSHA standards is to protect the worker from
injury or illness. These OSHA regulations should be recognized as job site requirements and fully complied with.
Failure to do so may result in substantial fines in the event of an OSHA inspection. Safe installation practices may be
further defined and made mandatory by state or local ordinances. Maintaining good housekeeping on the job site is
recognized as being important to both OSHA compliance and to successful job completion.
Walking & Working on Roof Panels
Placing Panels on the Structure
Do not place bundles of panels on the roof structure without first verifying the structure will safely support the
concentrated weight of the panels and the weight of the installation crew. Some roof structures may not be
designed to support the weight of a full panel bundle without additional structural support.
Walking on Roof Panels
An approved and safe walking platform should be used in high traffic areas to prevent the roof panels from being
deformed, scratched, or scuffed.
Do not use a roof panel as a walking platform. An unscrewed panel could collapse under the weight of a person
standing between purlins or at the end.
Do not walk on the last installed panel run, as the unsecured edge could collapse under a person’s weight. When
installing clips or making end lap connections, etc., stand where the roof structure will support your weight.
Do not leave a roof panel edge unattached, always install the clips to the panel before terminating the installation
for any period of time.
When using power tools, equipment, lanyards, retractable lines and other installation equipment, ensure that the
metal parts are covered in such a manner that they do not scratch the panel surface if dragged along the panel.
Panel Overhang
Do not stand on the end of unsupported (cantilevered) panels at the eave or ridge. Standing on the cantilever
portions may result in panel collapse.
Construction Loads
When properly attached to supporting structures and seamed, MSL panels are designed to support uniform loads
which are evenly distributed over the panel surfaces. Panels will also support a minimum 300 pound point load over
any one square foot area of any part of the panel.

GENERAL APPLICATION INFORMATION
The details shown on the following pages are suggestions or guidelines for installing the Mueller Snap Lock System.
The installation details shown here are proven methods of construction, but they are not intended to cover all building
requirements, designs or codes. The details may require changes or revisions due to individual project conditions.
Installation procedures shall be in accordance with instructions, details or approved shop drawings. Installers should
thoroughly familiarize themselves with all instructions prior to beginning the installation process.
The installer/designer is responsible for ensuring the following:
• That the details here meet the particular building requirements.
• Awareness of and allowance for expansion/contraction of roof panels.
• That adequate water tightness is maintained.
• That a proper uniform substructure is used to avoid panel distortion and that the substructure meets necessary
code requirements.
• That all supporting members have been examined and are straight, level, and plumb.
Due to the complexities of a standing seam roof it is the responsibility of the customer (or designer/installer) to
determine the suitability of the structure or substrate for a Mueller standing seam roof. It is the customer’s
responsibility to insure that their building is code compliant, properly engineered and constructed to facilitate the
installation of a standing seam roof. Standing seam panels offer little or no diaphragm stability to the structure and
cannot be relied upon for diaphragm support. Purlin stability is not provided by a Mueller Snap Lock panel. Accurate
sheet lengths and trim components are critical to a successful install and should be confirmed by the designer/
installer before any material is ordered.
7
Mueller can provide all flashings, trim and accessories shown in the installation drawings unless otherwise noted.
Panels, flashing and trim shall be installed true and in proper alignment with any exposed fasteners equally spaced
for best appearance. Sealant shall be field applied on clean dry surface.
Some field cutting and fitting of panels and flashings is to be expected in to be considered as a part of normal installation
work. In some cases extra length has been added to panels to ensure adequate product on the jobsite. Workmanship
shall be of the best industry standards with installation performed by experienced metal craftsmen.
Sealants
Sealants not exposed to direct sunlight should consist of either an elastic butyl rubber tape or non-shrinking, nondrying gum applied butyl. Single part urethane should be used when exposed to ultraviolet light. All sealant should
be applied clean dry services to ensure weather tightness. Sealant shall be installed as shown without voids.
Snow Design
The following details do not address snow load conditions. Special design consideration is required when installing a
metal roof in heavy snow environments. Contact your Mueller sales representative for more details.
Delivery and Storage
Handle panels in bundles with care. Do not use ropes or wires for lifting. Long panels (25 feet or more) may require
two or more lift points to avoid bending and buckling of panels. Store panels in a dry, well ventilated area. Elevate
one end of the panels to allow for drainage of any moisture. Block panels off the ground. Do not store panels in
direct contact with the ground. Do not allow strippable film to remain exposed to direct sunlight for any extended
period of time. Remove strippable film prior to, or immediately after installation of panels or trim. Do not walk
directly on standing seams. Wear shoes with non-marking/scuffing soles. Inspect each and every panel, trim and all
accessories before installation. Never install any product if it’s quality is in question. Notify your Mueller salesperson
immediately if any product is believed to be out of tolerance, specification, or has been damaged during shipment.
If there is a conflict between project erection drawings provided by Mueller and details in this manual, project
erection drawings will take precedence.

SAFETY AND STORAGE CONSIDERATIONS
As with all major construction projects, safety should be
a primary concern. The erector or contractor should be
sure that all OSHA safety rules are followed and that job
safety is strictly adhered to.
CAUTION
Care should be taken when cutting sheets.
Eye and hearing protection are important.
12
The following safety equipment is highly recommended
when installing metal roofing:
1. Safety rope and harness
2. Hand protection
3. Eye protection
4. Hearing protection
5. Soft rubber soled shoes
Metal roofing presents several specific safety issues:
1. Metal roofing is extremely slick and does not provide
firm footing. Extreme care should be taken when:
A. Working on roofs with very steep pitches.
B. Working on roofs when moisture is present.
C. Working on roofs when high wind is a factor.
D. Working with long panels.
2. Metal edges are very sharp and should be handled
with care.
3. Care should be used when lifting panels due to their
weight.
4. Always check for overhead electrical lines and exercise
care not to have metal sheets come in contact with
them.
5. All electrical tools should be inspected regularly for
damaged cases or frayed electric cords. Extension
cords should be inspected for damaged or frayed
insulation. Tools which do not meet good safety
standards should not be used.
NOTE
Always wear rubber soled work boots. When on
the roof, use OSHA approved protection devices
such as safety lines, safety nets or catch
platforms.
Storage: It is recommended that sheets be kept
covered and out of the elements if at all possible.
If sheets are to be stored outside, the following
precautions should be observed:
1. The storage area should be reasonably level, and
located so as to minimize handling.
2. When stored on bare ground, place plastic ground
cover under the bundles to minimize condensation
on the sheets from ground moisture.
3. Store bundles at least 12 inches above ground level
to allow air circulation beneath the bundle, and to
prevent damage from rising water.
4. Elevate one end of each bundle slightly to permit
runoff of moisture from the top of the bundle or from
between sheets. A waterproof cover should be placed
loosely over the bundles to allow for air circulation
under the cover.
5. Inspect stored bundles daily and repair any tears or
punctures in the waterproof cover.
6. Re-cover opened bundles at the end of each work
day to prevent subsequent moisture damage.
Unsecured Panels May Slip If Stepped On!
Never step on a single unsecured roof panel, or a stack
of roof panels laying unattached on the roof. Secure
each end of the panel with clamps or appropriate
fasteners.
Never Install Material if the Quality is in Question!
Checking order at time of delivery:
Check each order carefully, as it is unloaded. Report any
obvious damage or shortages to the carrier immediately.
If damage or shortages are noted after delivery (at
time of unpacking) notify your Mueller representative
immediately. Have invoice numbers and detailed
descriptions of the damage or shortage available.
These procedures are for your protection. A shortage
or damage discovered later can be caused by theft,
misplacement, mishandling or other causes and is not
the responsibility of Mueller, Inc.
Page 13
CARE AND HANDLING OF MUELLER SHEET METAL
Delivery: Mueller takes every precaution to ensure that material is delivered to the customer damage-free and fully
protected from the elements during shipment. When the material is delivered to the customer it then becomes the
customer’s responsibility to protect the material from the elements, possible theft, and other damage. The following
guidelines are recommended:
HANDLING: Proper care is required in unloading and handling panel bundles in order to prevent damage.
1. Bundles should remain banded (if possible) during the unloading process. Bundles should never be lifted by the
banding material.
2. Lift each bundle as close as possible to its center of gravity.
3. If the bundles are to be lifted with a crane, use a spreader bar of appropriate length and nylon band slings (do
not use wire rope slings as they will damage the material).
4. Depending on the panel length, some bundles may be lifted by a forklift. When using a forklift, the forks should
be spread to their maximum spacing, and the load centered on the forks.
Sheets over 25’ long require two forklifts.
5. After panel bundles are opened, individual sheets must be handled carefully to prevent panel buckling or damage
to the panel coating. When removing a sheet from a bundle it should be rolled off the bundle to prevent
scratching of the next sheet. Never drag or slide one sheet over another. Sheets should not be picked up by the
ends. Instead, lift the sheet along its longitudinal edge and carry in a vertical position. For sheets over 10’ long,
two or more people may be required to carry the sheet.
13
Wall and Roof Panels
Mueller’s wall and roof panels, including color coated, galvalume and galvanized, provide excellent service under
widely varied conditions. All unloading and erection personnel should fully understand that these panels are quality
merchandise which merit cautious care in handling.
Under no circumstances should panels be handled roughly. Packages of sheets should be lifted off the truck with
extreme care taken to ensure that no damage occurs to ends of the sheets or to side ribs. The packages should be
stored off the ground sufficiently high to allow air circulation underneath the packages. This avoids ground moisture
and deters people from walking on the packages. One end of the package should always be elevated to encourage
drainage in case of rain.
All stacked metal panels are subject, to some degree, to localized discoloration or stain when water is trapped
between their closely nested surfaces. Mueller, Inc. exercises extreme caution during fabrication and shipping
operations to ensure that all panel stock is kept dry. However, due to climatic conditions, water formed by
condensation of humid air can become trapped between stacked sheets. Water can also be trapped between the
stacked sheets when exposed to rain causing discoloration, often called “wet storage stain.” The stain is usually
superficial and has little effect on the appearance or service life of the panels as long as it is not permitted to remain
on the panels. However, moisture in contact with the surface of the panels over an extended period can severely
attack the finish and reduce the effective service life. Therefore, it is imperative that all panels be inspected for
moisture upon receipt of the order. If moisture is present, dry the panels at once and store in a dry, warm place.
Page 14
INSULATION
Insulation Installation:
When insulation is installed, the outside edge of the insulation should be tight against the outside edge of the
rake angle. A starter role of 4’ or 5’ is normally used so that approximately 12” of the leading edge will still be
exposed when a new run of insulation is installed. This allows easy access to the vapor barrier lapping of the
insulation. Four inches of the downhill end of the fiberglass blanket should be removed and the four inches of
vapor barrier folded back over the remaining blanket. This starting end of the insulation should be placed on
the inside, lower step of the edge plate and can be held in place with double-sided tape along the rake angle
and the eave plate.
NOTE: Blanket insulation omitted from the following pages for clarity.
